of his sweets when he discharged his chips
and water. He impressed upon me especi.
ally that il any accident brought me TO
q stand still with my battery the tempera-
ture Of the various vessels should be kept
above 1900 and below 1000; above 16O be-
cause ct that temperature fermentation
cannot take place; below 1000 because h0
found that if the juice was kept stewing In
the battery for any length Of time at that
high temperature it always gave trouble
i'll the pans and showed q falling of in the
return Of SsGsseOuite. / especially asked
both Mr.. Kolsmann and Mr.. Minchin about
the water question. They both laid stress
OIL the desirability of having good water;
but, added Mr.. Minchin, s'thRt is equally
true of the water with which you supply
your boilers. IF I could afford it would
filter all the water that went into my
diffusion battery, and / would also
treat she water which went to my boilers
In the same way" He told me that two or
three years ago, when they ran short OF
water at Aska, he used all his con.
denser water-I mean, not condensed water,
but the water which was pumped through
his COndensers for diffusion, and found
scarcely any appreciable dimiaut;On Of
sugar as the result. / may further men.
ton that, o few months ago, while they
were trying diffusion in Australia in con.
nectiOn with q plans erected by the Fee.
Lille people, they ran short OF water and
actually used over and over again she
liquid-I can hardly callit water-which
they obtained by passing the exhausted
chips through their mill. OF course, this
must awe been full Of impurities, yet the
proprietor of the estate was 30 pleased
with the results which he obtained, even
under such adverse circumstances, that
he has, ! understand, ordered q second
battery from the Fires Lille people. The
water usually used at Aska 10 perfectly
clear river water, and it goes from the
battery into the sulphur boxes perfectly
clear, resembling very fine hook in colour,
and as different from the green liquid which
we get from our mills as any thing can pos:
sibly be. Mr.. Minchin knows that che
moment the smallest tendency to cloudi.
ness or an appearance of feRthery streaks,
occurs in his diffusion juice, that something
10 going wrong with his battery. The diff.
fusion Juice is drawn from the battery into
the measuring tank, passes through the
sulphur boxes, where about so lbs. of sui
phur are burnt in the "a hours, and runs
into the defecatOr holding $50 gallons.
where Ii gallons of lime water, standing
Mt Is Beaume is added, and the liquid lie
brought up to boiling point. Very little
skimming Yns necessary, and the scum
was so small in quantity that the product
Of $50 gallons could all be taken away in
o single galvanized bucket. Mr.. Kollmann
explained this absence of SCUM by saying
that the bulk Of the mucilage aud albumen
was left in the chips. Albumen cOagulates
at 1909 F., and as the battery there Ia
worked above that temperature the bulk
Of the albuminous matter becomes fxed in
the chips. "You won't know" said he to me,
''what o good thing you have got in dihu-
sion until you come to deal with the juice.n
From the defecators the juice, standing
at about 81 Beaun6, was run through
bag filters, 100 being kept ct work for "a
hours and purifying the product of about
1870 tons Of zane. | got some of these bags
just as they were being changed, and wo
weighed the slush found in them. From
Is to Is lbs. Of wet mud were taken
from each OF them. and this when dried
gave only 8 lbs. Of hard dirt as the re-
suit Of say, one ton ~of,diffusion juice. This
shows, I think, that no very large amount
OF impurity could have been left in the
juice; SO the absence of scum cannot be
explained in that way. The juice was
then run from the concretor battery. IL
generally went on The battery at SO
Beauln6, and after remaining "a minutes in
transitu Came of atal1o Beaum6. Two
batteries easily performed the whole work
